Which is best for your requirement?
Its documented integration/function time scope fits your measured workload and the caveats shown in the comparison.
Its documented execution or account model better matches the exact requirement rather than a vendor-wide headline.
Test payload, duration, throughput, concurrency, failure behavior, billing scope, and recovery with representative traffic.
Validate the decision with your workload
Before choosing between AWS API Gateway and Vercel, reproduce the comparison with the exact plans, models, regions, runtimes, and invocation paths you intend to operate. The reviewed rows cover integration/function time and payload; they do not turn different pricing, reliability, developer experience, or ecosystem tradeoffs into one universal score.
- Capture representative request sizes, token usage, duration, concurrency, storage, and failure behavior at realistic percentiles.
- Test the boundary and the recovery path on both candidates, including throttling, timeouts, partial failure, retries, and cost controls.
- Record which scoped observation drove the choice and recheck its official source before migration or a major traffic increase.
